No one may threaten or commit violence ('aggress') against another man's person or property. Violence may be employed only against the man who commits such violence; that is, only defensively against the aggressive violence of another. In short, no violence may be employed against a non-aggressor. Here is the fundamental rule from which can be deduced the entire corpus of libertarian theory.

It is not the business of the law to make anyone good or reverent or moral or clean or upright.

Free-market capitalism is a network of free and voluntary exchanges in which producers work, produce, and exchange their products for the products of others through prices voluntarily arrived at.

One of the most important features of our economic resources is their scarcity: land, labor, and capital goods factors are all scarce, and may all be put to various possible uses. The free market uses them 'productively' because the producers are guided, on the market, to produce what the consumers most need: automobiles, for example, rather than buggies.

Gold was not selected arbitrarily by governments to be the monetary standard. Gold had developed for many centuries on the free market as the best money; as the commodity providing the most stable and desirable monetary medium.

This process, this method necessary to man's survival and prosperity upon the earth, has often been derided as unduly or exclusively "materialistic." But it should be clear that what has happened in this activity proper to man's nature is a fusion of "spirit" and matter; man's mind, using the ideas it has learned, directs his energy in transforming and reshaping matter into ways to sustain and advance his wants and his life. Behind every "produced" good, behind every man-made transformation of natural resources, is an idea directing the effort, a manifestation of man's spirit.

Pollution and overuse of resources stem directly from the failure of government to defend private property. If property rights were to be defended adequately, we would find that here, as in other areas of our economy and society, private enterprise and modern technology would come not as a curse to mankind but as its salvation.
